Green Lantern Lantern and Ring 
SUMMARY 

One of my friends is a fan of the Green Lantern, and he thought it would be cool to have a 
glowing ring that charges when put inside a lamp. I realized that I already had something 
similar in my Upgraded Indestructible LED Lantern project, so I decided to build it. 



Step 1 — Green Lantern Lantern and Ring 




• First, build the wireless charger from step one of Upgraded Indestructible LED Lanterns . 
Make sure to follow all the directions, or you will fry your transistors.

Step 2 




• Now, build the receiver following this schematic. 

• Glue the indicator LED and switch to the side of the battery. 

• The coil is going to be the ring, so have the inside diameter a little larger than a normal 
ring, and wrap it in electrical tape. 

• Print out a Green Lantern symbol and glue it on top. Wrap the rest of the ring except the 
switch and LED in electrical tape. 

• Yes, I am aware that my ring looks terrible and is in no way accurate. The ring pictured 
was thrown together after I had already given the real one to my friend and realized that I 
had not taken any pictures of it for this guide. The one I gave him was made from molded 
plastic and frosted glass, and looks more like the real thing.

Step 3 




• Now glue the 2" coupling to the center of the 1 1 /2" tee, threaded side out. 

• After it dries, sand the outside of both pieces. 

• Apply a coat of primer to the outside, then black paint. I suggest multiple coats.

Step 4 




• Place the wireless sender inside 
the tee, so that the coil lies flat in 
the center. 

• Cut or drill a small hole or notch in 
the bottom of the tee, and run the 
power supply to the sender out of 
it. 

• Drain the battery in the ring, then 
flip the switch off and place it 
inside the lantern. The indicator 
LED should light up 

• After about 15 minutes, pull it out 
and turn the switch on, the high- 
brightness green LED should light 
up. 

• If it does, you're done! If not, flip 
the ring over and put it back. If that 
doesn't work, check your wiring. 

• *Optional* Drill two holes near the 
top of the lantern on opposite sides 
and run a large loop of black wire 
from one to the other to make a 
handle. 



Unless you modified an accurate ring, I wouldn't take this to a convention, but it is a cool little 
thing to have.
